  Switch statement

  Demonstrates the use of a switch statement.  The switch statement
  allows you to choose from among a set of discrete values of a
  variable.  It's like a series of if statements.

  To see this sketch in action, but the board and sensor in a well-lit
  room, open the serial monitor, and and move your hand gradually down
  over the sensor.

  The circuit:
  * photoresistor from analog in 0 to +5V
  * 10K resistor from analog in 0 to ground
